Oh, I remember this game! I used to play this for abit when I was younger. I thought it was pretty fun, as at the time I was (and still am) pretty into card games. Though, I was hoping for more game over type of endings.

its all japanese XD
don't get much how to play~
piking cards until a monster comes..
then fight killing it nothing happens
getting killed nothing happens

found some help to the game:

the attacks:
By list they go as:
Fire ( can't use at start due to fear of it )
Ice/Water
Lighting
Wind
Escape ( Allows you to run away from a fight )
Heal
Blink ( For a short while when it activates you'll dodge all attacks )
Protect (?) lowers ac

ac = hit rate. the lower it is the less u get hiten

i the shop u can use the green stones an money to raise some stats but i don't know which-.-
